2. The electronic shelf label controlling system according to claim 1 , wherein the relationship between the label identifying information and the label location information is created by the controlling device.

3. The electronic shelf label controlling system according to claim 1 , wherein the relationship between the label identifying information and the label location information is created by the deploying device.

4. The electronic shelf label controlling system according to claim 1 , wherein the first electronic shelf label is used for displaying a label displaying information, the controlling device is further used for storing a label content table, and the label content table records a relationship between the label location information and the label displaying information.

5. An electronic shelf label installing method, comprising: obtaining a label identifying information of a first electronic shelf label; obtaining a label location information according to a location of the first electronic shelf label on a shelf; creating a relationship between the label identifying information and the label location information; and changing a label location table according to the relationship between the label identifying information and the label location information; wherein the step of obtaining the label location information includes: obtaining a location code of the first electronic shelf label by performing a mathematical interpolation on a second electronic shelf label and a third electronic shelf label if the second electronic shelf label and the third electronic shelf label are disposed at two sides of the first electronic shelf label, wherein the location code of the first electronic shelf label is between a location code of the second electronic shelf label and a location code of the third electronic shelf label, and a shelf code of the second electronic shelf label and the location code of the first electronic shelf label are combined to be the label location information.

6. The electronic shelf label installing method according to claim 5 , wherein the step of obtaining the label location information includes: obtaining a location code according to an initial value if only the first electronic shelf label is disposed on the shelf, wherein a shelf code of the shelf and the location code of the first electronic shelf label are combined to be the label location information.

7. The electronic shelf label installing method according to claim 5 , wherein the step of obtaining the label location information includes: obtaining the location code of the first electronic shelf label by performing a mathematical extrapolation on the second electronic shelf label if the second electronic shelf label is disposed at one side of the first electronic shelf label, wherein the location code of the first electronic shelf label and the location code of the second electronic shelf label are incremented or decremented, and the shelf code of the second electronic shelf label and the location code of the first electronic shelf label are combined to be the label location information.

8. An electronic shelf label updating method, wherein a label content table records a relationship between a first label location information and a first label displaying information of a first electronic shelf label, a label location table records a relationship between a first label identifying information and the first label location information of the first electronic shelf label, and the electronic shelf label updating method includes: changing the label content table by changing first label displaying information; looking up the changed label content table to know whether a second electronic shelf label is needed to be installed, or the first electronic shelf label is needed to be removed; obtaining the first label location information according to the changed label content table, if the second electronic shelf label is not needed to be installed and the first electronic shelf label is not needed to be removed; obtaining the first label identifying information corresponding to the first label location information according to the label location table; transmitting the changed first label displaying information to the first electronic shelf label; and transmitting a product transferring instruction to the first electronic shelf label.

9. The electronic shelf label updating method according to claim 8 , further comprising: obtaining a second label identifying information of the second electronic shelf label, if the second electronic shelf label is needed to be installed; obtaining a second label location information according to the location of the second electronic shelf label on a shelf; creating a relationship between the second label identifying information and the second label location information; changing the label location table according to the relationship between the second label identifying information and the second label location information; determining whether the second label location information is identical to a third label location information corresponding to the second label displaying information in the label content table; and transmitting a second label displaying information which is added to the label content table to the second electronic shelf label, if the second label location information is identical to the third label location information corresponding to the second label displaying information in the label content table.

10. The electronic shelf label updating method according to claim 9 , further comprising: transmitting an error information to the second electronic shelf label, if the second label location information is not identical to the third label location information corresponding to the second label displaying information in the label content table.

11. The electronic shelf label updating method according to claim 9 , further comprising: transmitting the product transferring instruction to the second electronic shelf label.

12. The electronic shelf label updating method according to claim 8 , further comprising: obtaining the first label location information corresponding to the first label displaying information according to the label content table, if the first electronic shelf label is needed to be removed; and obtaining the first label identifying information corresponding to the first label location information according to the label location table.
